Application filed October 2451905. Serial No- 284 172.

It is customary in. many retail establish- I ments to render bills to customers at long intervals, but to enter the items upon said bills at the time when the goods are sold. ,thus necessary where the bills are made out on. writing-machines to insert the same bill in the machine once for each item, so that in many cases a bill has to be inserted and removed from the machine a great many times in the course of a week or month. After the first item has been written and the bill removed from the machine it becomes necessary to replace the bill in the machine accurately with reference to the printing-point, so that the second item will fall precisely in alinement with theiirst in order to preserve an even appearance of the columns of writing andfigures. Heretofore it has been necessary each time that a bill was inserted to adjust the bill until the previously-mitten line thereon registers gradually with the usual platen-scale. While this adjusting operation is but a small matter, still Where the bills are inserted and removed from the machine once for each item written thereon the necessity of adjusting the billlin the usual manner becomes highly objectionable.

The object of my invention is to avoid the necessity for such adjustment and to enable the bills when put in the machine to be adjusted instantly and Without appreciable labet or attention to exactly the required position with reference to the printing point or line and also with reference to the usual tabulating' mechanism which is commonly employed in writing bills.

In carrying out my invention I providev at the delivery side of the revoluble platen a gage, against which the leading edge of the paper may abut'as it emerges from the ma- 0 machines, and

It is chine, and I also provide one or two gages for the side edges of the paper, and preferably I provide in connection with said gages a plate or tablet extending along the top of the platen and fixed upon the carriage-frame. for convenicnce in adjusting the paper to the gages. In theaccompanying drawings, Figure 1 1S Patented Sept. 4', 190a.

elevation of the device.

In said Underwood machine a revoluble cylindrical platen 1 is mounted in ends 2 3 of the platen-frame, which is mounted upon a carriage 4. Extending between said ends is a bar 5, upon which is mounted a tablet or plate 6, which extends along the platen and overhangs the rear thereof. At its rear edge said plate is bent up to forma ledge 7 to serve as a gage against which theleading edge of the paper may abut, and at its sides said plate is bent up to form ledges :8 9, constituting gages for the side edges of t-hepaper.

In operation a bill or sheet 10 is inserted between the platen and the usual rear inclined paper-shelf 11 and passes up around the front. of the platen and back over the same. The usual pressure -roll crs 12 13 being cast oi'l' in the usual manner by depressingbut the latter are closer together than the gages 15 16 and may be so related that the paper fits accurately between them. This operation of inserting and adjusting the paper can be accomplished very quickly and without labor or thought, and it will be understood that no matter how many times the same bill is inserted it always comes to eX- actly the same place with reference to the rinting-point, which in this instance is the ont of the platen where the types 17 strike.

When the paper is so adjusted, the handle 14.

maybe lifted, thus bringing the pressure-rollers 12 13 into action, and thereupon the time.

. laten may be rotated by the finger-wheel 18 orwardly until the last previously-written line is brought to or above the rinting-point. Thus it will be seen that the bi l is always adju'sted with absolute accuracy with reference not only to the printing-point, but also to the usual tabulating mechanism, so that the operator is called upon to give but a minimum of attention to positioning the. paper, and hence a relatively large amount of work of this class may be accomphshed in a given The invention is of particular value where carbon copies of the bills are made u on sheets'of eater width than the bills, t e ga es 8 an 9 being so spaced that the large s eets fit between them, while the narrow bills may be set against either gage 8 or 9, as the case may be. It will be seen at Fig. 2 that the plate 6 and gage 7 are below the path 19, usually taken by the aper in emergmg from the machine, so t at the gage' 7 does not interfere with the advance of the paper. 7

he gages and tablet may be variously formed and mounted, and in some cases the tablet'may be omitted. it is not necessary in all cases that the side gages be employed in connection with the front gage 7. In some cases one of the side gages may be omitted.

It will be seen that thegages are in plain sight, so that the manipulation of the paper can be both quick and exact. When one item or charge 15 written, the pressure-roll-release'key 14 is depressed, thereby dropping the pressure-rolls away from the platen to permit the Withdrawal of the sheet, and while said rolls remain released the next sheet is slipped down between the platen and the plate 11 and around beneath and up in front of the platen, when the leading portion is pressed by the operator down upon the tablet 6 and adjusted to the gages. 14 is lifted and the platen turned until the proper point u on the bill is brought to print- 1ng position. t will be understood that the usual releasable means 19 are employed in said Underwood machine for guiding the sheets u in front of the platen. The 0 era tion of s ipping the paper around the p aten is performed very quickly and much rolling of the platen is also saved, which is an advantage, since it is the practice to insert a carbon and a record sheet together with the bill, and as the bill may be inserted twenty or thirty times before completion it will be seen "hat it is a desideratum to avoid much rolling Qf the platen at each insertion, because it tends to injure or wrinkle the carbon-paper and to cause the latter to offset unduly upon the record-sheet.
